Alt, Alt Energy

And you thought corn was innovative. Here are four new forms of energy that'll really blow your mind. (One of them is a floating wind farm.)

Seawater Jet Fuel

The United States Navy has been researching the most effective method of separating hydrogen and oxygen in order to make hydrocarbons, a key ingredient in jet fuel. The U.S. Navy estimates the cost per gallon at $3.00 to $6.00, which is roughly the same as non-ocean water jet fuel.

Floating wind farms

After the 2011 Fukushima nuclear power incident, various countries have begun looking into the possibility of replacing nuclear power with wind power.

Currently, some countries are looking into developing floating windmills that aren't directly attached to the ocean floor—instead, they'll float with a buoyancy mechanism and will be anchored with lines to the sea floor.
